Creation of Info.plist files through Xcode is more canonical and
future-proof, as it will automatically pick up changes/updates
introduced by Apple. Non-standard keys can still be added via a
template file, which will then be extended by Xcode with the default
keys.
The FTL SDK is outdated and not actively maintained - the warnings are
known and acknowledged, so there is no need to further pollute the
build output with them.
